CTI 2572-A Installation and Operation Guide V1.3 81
HEX DEC DESCRIPTION SOLUTION
029D 669 CMD TIMEOUT ERROR
The time to process the requested command
exceeded the Command Timeout value.
Command processing has been halted.
Note that the timeout value may have been
explicitly set in the Command Block or the default
may have been used (timeout = 0).
If you are using UDP, your first attempt to send a
message to a newly referenced node may time out
while the 2572-A is performing address resolution.
Retry the command.
In some circumstances, you may occasionally get a
timeout error, especially with heavy local network
traffic or slow remote data links. In these
circumstances, your logic should retry the
command.
This error may indicate a bad connection (faulty
cable, loose connector, etc.). Check all cabling
carefully.
If the error persists and you have explicitly set the
timeout value, it is possible that you have set the
timeout value too small. Try increasing the value or
using the default value.
If you are using multicast, ensure that you are using
the Unacknowledged Write command not one of the
other Word Transfer commands.
029E 670 ALREADY BUSY ERROR
The protocol manager received a new command
prior to the completing the previous command.
This error can also be produced by simultaneously
triggering two command slots which reference the
same command block.
If more than one command slot is used, make sure
that they reference different command blocks and
that the command blocks that they reference have
different connection numbers.
02AC 684 MEMORY READ ERROR
The 2572-A was unable to read the requested V
memory.
If this occurs on a WRITE REMOTE command
block, it indicates that the 2572-A could not obtain
the data from the local PLC V memory.
If this occurs on a READ REMOTE command
block, it indicates that the memory in the remote
device could not be read.
When this error occurs, it is usually due to an invalid
memory address specification in the command
block. Check the value for Source in Offset 3 and
make corrections if necessary.
When this error is returned in response to a READ
REMOTE command block, it is also possible that
there is a problem in the remote PLC which
prevents the 2572-A from reading V memory. Retry
the command. If the problem persists, check the
remote device.
02AD 685 MEMORY WRITE ERROR
The 2572-A was unable to write the requested
memory.
If this occurs on a WRITE REMOTE command
block, it indicates that the remote device could not
write the data into remote memory.
If this occurs on a READ REMOTE command
block, it indicates that the local PLC could not
write the result from the remote device into local
V memory
When this error occurs, it is usually due to an invalid
memory address specification in the command
block. Check the value for Destination in Offset 5
and make corrections if necessary.
When this error is returned in response to a WRITE
REMOTE command block, it is possible that there is
a problem in the remote PLC which prevents the
2572-A from writing V memory. Retry the
command, if the problem persists, check the remote
device
02B9 697 UNABLE TO ADD COMMAND TO ACTIVE LIST
The module is unable to process this command.
If this occurs, the cause may be a module firmware
error. Contact CTI if the error persists.
02BA 698 MINIMUM PRODUCTION INTERVAL OUT OF
RANGE
The value you specified for the minimum
production interval is less than 50 or more than
10,000.
Enter a valid value in the command block and re-
execute the command.
02C7 711 COMMAND INPUT QUEUE FULL This may occur when commands arrive at the 2572
or 2572-A faster than they can be processed
